Then this was very important information you should have mentioned in
the first place. You told us originally you were trying to use python2,
now you're claiming you're actually using jython.

jython and python2 have nothing to do with each other. They don't use
the same pythonpath, and jython can be installed without having python2
installed at all.

jython ships its own independent copies of the standard library,
byte-compiled into Java .class files instead of cpython .py files, and
actually does include its own imp.py file which simply imports from
jython.jar at org/python/modules/_imp.class

I can just as easily import imp on jython as I can on python2 or
python3. It's part of the stdlib, any python implementation (cpython,
jython, pypy) is *required* to have it.
